Description

Technical Field

[0001] This application belongs to the technical field of containers, and particularly relates to a snap - on container corrugated board. Background Art

[0002] In the field of container manufacturing, corrugated board, as a unique steel plate material, is widely used in the construction of container outer shells due to its light weight, high strength, easy processing and other characteristics. However, although the corrugated board in the existing technology shows certain advantages in enhancing the overall structural strength of the container and reducing weight, in the actual splicing and assembly process, its inherent structural design faces significant challenges and deficiencies.

[0003] Specifically, when the corrugated boards in the current market are spliced into the container outer shell, there are often problems of low splicing efficiency. This is mainly because the splicing method of traditional corrugated boards is relatively cumbersome, and may require complex alignment and fixing steps, thus increasing the assembly time and cost. In addition, due to the lack of fine design or insufficient sealing measures at the splicing interface, after splicing, the outer shell structure of the container is prone to water ingress. This not only damages the protective performance of the container, but also may have an adverse impact on the goods loaded inside, such as dampness, mildew, etc., thus affecting the safety and quality of the goods.

[0004] In view of the above problems, the industry urgently needs an improved corrugated board structure, aiming to improve the splicing efficiency and enhance the sealing performance at the splicing point to ensure that the container can maintain good structural integrity and protective ability under various transportation conditions.

It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0026] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0027] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0028] In order to illustrate the technical solution described in this application, the following will be illustrated through specific embodiments.

[0029] Please refer to Figures 1 to 5 As shown, the embodiment of this application provides a snap-on container corrugated board, including a corrugated board body 10. The corrugated board body 10 includes a plurality of trapezoidal plates 11 and a plurality of flat plates 12, and the plurality of trapezoidal plates 11 and the plurality of flat plates 12 are alternately connected.

[0030] On both sides of the corrugated board body 10 are respectively a flat plate 12. A part of one flat plate 12 is bent inward by 90° to form an L-shaped connecting part 121, and a part of the other flat plate 12 is bent outward by 90° to form a U-shaped connecting part 122. Welding holes 123 are provided on both the first folded edge 1221 and the first bottom edge 1222 of the U-shaped connecting part 122.

[0031] The L-shaped connecting part 121 of one snap-on container corrugated board is used to be embedded in the U-shaped groove of the U-shaped connecting part 122 of another snap-on container corrugated board, and the fitting part of the two is welded and connected through the welding hole 123.

[0032] As an example, the corrugated board body 10 is made of steel plate.

[0033] As an example, the width of the flat plate 12 is 63 mm, and the widths of the upper base and the waist of the trapezoidal plate 11 are 63 mm and 35 mm respectively.

[0034] As an example, the widths of the first folded edge 1221, the first bottom edge 1222, and the second folded edge 1223 of the U-shaped connecting portion 122 are 25 mm, 20 mm, and 10 mm respectively; the widths of the third folded edge 1211 and the second bottom edge 1212 of the L-shaped connecting portion 121 are 24 mm and 15 mm respectively.

[0035] Specifically, the L-shaped connecting portion 121 and the U-shaped connecting portion 122 add two vertical ribs for force bearing to the container shell structure, making it have stronger anti-extrusion ability and also enhancing the impact resistance of the plate.

[0036] Specifically, the L-shaped connecting portion 121 is embedded in the U-shaped connecting portion 122 and fixed by welding, with fast installation speed, higher precision, and higher efficiency.

[0037] Specifically, due to the snap-together assembly method, a vertically sunken gap will be formed on the outer side of the carriage, which is more convenient for external intermittent welding and waterproof sealant application.

[0038] Specifically, in the snap-together assembly process, the L-shaped connecting portion 121 is embedded in the U-shaped connecting portion 122 and fits tightly, forming two waterproof barriers. In the case where the glue layer on the outside of the carriage is damaged, it greatly reduces the risk and amount of water entering the carriage interior.

[0039] Specifically, welding and fixing are carried out through the welding holes 123, which greatly reduces the welding workload compared to traditional overlapping welding. And the welding orientations are flat welding and side welding. The vertical welding orientation has stronger force bearing, greatly reducing the probability of the carriage bulging or bursting, making the carriage more durable.

[0040] In summary, the above-mentioned snap-together container corrugated board, by embedding the L-shaped connecting portion 121 into the U-shaped connecting portion 122 and welding and fixing, has the advantages of convenient installation, durability, low risk of carriage bulging or bursting, and low risk of air and water ingress.

[0041] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included within the protection scope of the present application.
